. IMPROVEMENT IN' vMODE OF ATTAOHING OALKS TO HORSES SHOES.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM JONES BERNE, of Cincinnati, in the county 4of Hamilton, and State of Ohio, have invented anew and useful Improvement in Adjustable Calks for Horse-Shoes; and 1 do her'eby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, makingfpart of this specification, in which- I l Figure 1 is a side elevation.

Figure 2 is a. front elevation, and

Figure 3 is a bottom view.

In all the figures the same letters are employed in the indication of parts which are identical.

The object of this invention is to provide callas which may be adjustably attached to the ordinary horseshoe without removing t-he shoe when the roads are covered with ice, and which may be readily removed when not needed.

AFA are metallic sockets, which are so form-ed that they may he slipped over the-heel calksof an ordinary horse-shoe'. On the bottom ci' these sockets I place steel corlcs A, made sharp and of any suitable form,iand

of suilicient length to give the animal secure footing upon the ice. B is a metallic plate, bent around the toe of the shoe, and extending from the frontof the hooiI under the shoe,.and carried upwards under" the hoof. Rods Bl are attached to the upper corners of this'plate; and projecting upwards, he'ar threads cut upon their upper end to receive a nut. A sharp steel calk is attached4 underneath this plate, immediately below the t-oe of theV shoe at B2. C C are metallic straps formed each with an eye in the front end, through which the rods B pass. These straps are respectively attached to the sockets A by a'pivot, on which they turn. The front ends of the straps may be united by a rod passing through them, with nuts on the end thereof, to dra-w them together, and

rel iev e the rods B from side strain. The lower and hindermostend of the plate B is pivoted to two parallel cross-pieces D, 'which arel located with each end under andresting against the lower side of theshoe on each side oi' the hoof. The piece D *may be made in a single piece, with a recess 4to receive the end of the plate B, o r the' latter may be pivoted toit. i

When the adjustable c allfts are to be attached to the shoe the plate B is placed under the toe, and the cross- The sockets A, with the straps C, are slid over the heel of the shoe, and the Astraps carried foward and attached to the rods B1, and-the whole securely fastened to the shoe hy tightening the nuts. l i Y What I claim as my invention, and desire to secure hy Letters Patent, is Adjustable calks, which may heapplied, to ordinary horsefshoes, without removing the latter, by means of the sockets A, toe-piece B, cross-piece D,'and straps C, substantially as described.

Inytestimony whereot'I have signed my name to this specication in the presence of two subscribing Witnesses WILLIAM JONES BERNE.
